Can urethral prolapse resolve on its own?

Mild mucosal eversion may appear to improve temporarily, but persistent redness, blood in the urine, or difficulty urinating typically requires veterinary assessment to prevent complications. Consult your vet if you are unsure.

What tests will the vet perform during the visit?

The vet will usually perform a physical examination, blood tests, and urinalysis, and may arrange imaging (X-ray or ultrasound) and urine culture to determine whether there is an infection or obstruction.

How long will follow-up monitoring be needed after surgery?

The frequency of post-operative follow-up varies by case. Generally, wound healing and urinary status need to be monitored over the weeks to months following surgery, with further tests scheduled as directed by your vet.

How can I reduce the risk of recurrence at home?

Increasing water intake, maintaining good urination habits, and completing the full course of antibiotics or follow-up visits as directed by your vet can help reduce the risk of infection and recurrence. Contact your vet if you notice anything unusual.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Seek Emergency Care Immediately

•Complete inability to urinate or persistent straining with no urine output
•Heavy bleeding from the genital area or in the urine
•Lethargy, persistent vomiting, or unresponsiveness

Schedule a Clinic Visit Soon (within 24–72 hours)

•Obvious redness and swelling of the protruding penile or urethral mucosa
•Blood in the urine or visible blood streaks during urination
•Frequent, short urge to urinate with only small amounts passed

01What symptoms indicate something is wrong?

Urethral prolapse typically presents as eversion or protrusion of the penile or urethral mucosa, accompanied by blood in the urine, difficulty urinating, or repeated straining to urinate.

Visible protrusion, redness, or eversion of the penile or urethral mucosa
Blood in urine or blood streaks/clots when urinating
Straining to urinate, frequent attempts with small urine output each time
Persistent licking of the genital area or signs of discomfort when touched
Decreased activity or becoming quiet and withdrawn due to discomfort

Seek emergency care immediately if you notice the following symptoms:

⚠️ Complete inability to urinate or repeated attempts with no urine produced
⚠️ Heavy bleeding from the genital area or in the urine
⚠️ Lethargy, persistent vomiting, or unresponsiveness

02How to assess the situation at home: observation tips and emergency criteria

Observing and recording key information at home before your vet visit can help the veterinarian assess the situation quickly and plan appropriate tests.

Note the time symptoms were first noticed and how they have changed
Take photos of the genital area and videos of urination to show the vet
Estimate the number of urination attempts per day and any changes in urine volume
Record any changes in water intake, appetite, and activity level
Seek veterinary care immediately if symptoms worsen or your pet cannot urinate

03How will the vet make a diagnosis? Common diagnostic tests

The vet will begin with a physical examination, supplemented by blood tests, urinalysis, and imaging to assess the severity and check for concurrent infection.

Physical examination

assessment of the genital area, palpation of the bladder, and evaluation of pain response

Blood tests and complete blood count (CBC)

assess overall health and signs of anaemia or infection

Urinalysis and bacterial culture

confirm the presence of infection or determine the source of haematuria

X-ray or ultrasound

evaluate the bladder, urethra, or related pelvic abnormalities

Further examination or procedures under anaesthesia if needed (e.g. catheterisation or surgical repair)

04Treatment and aftercare: medication, dietary changes, and home care guide

Treatment may include medication to control infection and pain, or surgical repair when conservative management is unsuccessful. Post-operative monitoring and repeat urinalysis are important.

Antibiotics and pain medication to manage infection and pain and improve urination
Surgical repair if conservative management fails or prolapse recurs
Dietary adjustments and increased water intake to support urinary tract health
Regular follow-up visits and repeat urinalysis after surgery or treatment
Referral to a specialist hospital or surgeon for further evaluation and long-term monitoring is recommended

05What to prepare before seeing the vet: key information to help the vet quickly identify the cause

Write down when symptoms started, how often they occur, and how they have changed

Prepare a record or notes on the number of urination attempts and estimated urine volume

Bring photos of the genital area and urination videos to the clinic for the vet to review

List any medications, supplements, and known allergies your pet currently has

Call ahead before your appointment to confirm whether culture testing and imaging are available
